Delta printer

The [stepper] sections requires the following parameters to be set:

• step_distance: defines the length in mm of a single step. If you are unsure check the Klipper FAQ
• position_endstop: distance (in mm) between the nozzle and the bed when the nozzle is centred and touching the bed
• arm_length: length (in mm) of the diagonal rod that connects this tower to the print head.
• dir_pin: Specifies the stepper direction. The stepper motors direction depends on your printer configuration. The direction can be inverted adding “!” in front of the pin name. For instance, stepper_a is inverted by configuring the dir_pin to !PA6

[stepper_a]
step_distance: .0125
position_endstop: 297.05
arm_length: 333.0
dir_pin: !PB5

[stepper_b]
step_distance: .0125
position_endstop: 297.05
arm_length: 333.0
dir_pin: PA15

[stepper_c]
step_distance: .0125
position_endstop: 297.05
arm_length: 333.0
dir_pin: !PB12

The [printer] section that you will find in your configuration file if you have selected the Delta file. The default values should work on every machine, but delta_radius shall be updated to the one of your machine.

• max_velocity, max_accel: define the performance of the X and Y moves (in mm/s and mm/s2)
• max_z_velocity: define the performance of the Z moves (in mm/s)
• delta_radius: projection of the diagonal rod onto the XY plane, when the effector is centred (in mm)
